► Way to Venus: the RTG

Space Apps Challenge 2022 – team “134”

→ Main components

We need two components: the power source and thermal insulation.

​

The first one will be Multi-Mission Radioisotope Thermoelectric Generator.

The second one is polycrystalline fiber.

Our main idea is to use the RTG – Radioisotope Thermoelectric

Generator as a power source. It can serve for more than 10 years, despite having quiet low coefficient of performance.

​

The RTGs work by converting thermal energy into electrical energy.

​

Also, the RTG isn’t affected by high temperatures and pressures, which is very important for our Venus mission.

→ Polycrystalline fiber (PCW)

PCWs are made primarily of aluminum (content typically 72-99% in the oxide form), with the remainder composed of silicon.

​

It can withstand temperatures up to 1200º С and is resistant to chemical damaging, oxidizing or atmospheric environments. General applications include ceramic furnaces and furnace linings.

→ Conclusion

Our project will work quite efficiently and for a long time, since the use of RTGs is an excellent example of the application of nuclear processes.

​

Thermal insulation will allow the RTG not to heat up to high temperatures of the planet, so the RTG will not be damaged and will be an excellent battery for a rover or lander.
